The process of bit-shifting and resetting the leftmost bit to 1 when a page is referenced is known as the "aging" or "clock" algorithm. This algorithm gives a history of each page's usage by maintaining a counter for each page that increments when it is referenced and periodically shifts the bits to the right. The leftmost bit acts as a reference bit that indicates whether the page has been referenced recently. Therefore, the statement in the question is true.
